Kepler's theory was " All planets revolve around the sun in elliptical orbits, and he also believe that the sun was not the exact center of the universe."
Kepler's Life
Kepler was born on December 27, 1571 in Stuttgart, Germany.
Kepler was rasied by his father who left him to fight the eighty year war.
His mother was tried for witch craft.
Kepler moved in with his grandpa.
Kepler was introduced to astronomy very early in his life.
When Kepler was 6 years old he saw the great comet of 1577, and when he was nine Kepler saw the lunar eclipse.
Kepler got a very good eduction in math and astronomy at University of Tubingen and was offered job when he was 24 at Graz, Austria.
When Kepler was 24 he wrote a book in which he defened the Copernican theory.
Johannes Kepler died on November 15, 1630 at the age of 58.
Kepler's laws of motion
Kepler's first law of plantary motion is, The orbit of every planet is an ellipse with the sun at a focus.
The second law is, A line joining a planet and the sun sweeps out equal intervals of times.
Last law is, The square of the orbital of a planet is directly proportional to the cube of the semi-major axis of it's orbit.
OTHER FACTS! Kepler got smallpoxs at a very young age.
Another thing is, Kepler scientific contribution is a treatise on optics as applied to telescope lenses, in 1611.
